SURVEY & Hydrographical Mapping
Seabed Mapping
With experienced staff covering all aspects of our seabed mapping we can offer the best services available in the market.
Site Surveys (Drilling Hazard Surveys)
Data from drilling hazard surveys is acquired with the aim of supporting plans for rapid development. Detailed knowledge of the potential hazards which may affect a drilling rig is critical during offshore exploration and production of oil and gas. Key considerations are:
Spud Scan
- Shallow gas
- Anchoring conditions
- Top hole stability and Spudcan Analysis
- Foundation of jack uprigs
- Gashydrates
- Soil/slope stability
Geophysical and Hydrographic Survey Services
The near shore and shallow water environment presents unique problems for detailed seabed and sub-sea assessments critical to cost-effective design and installation of marine construction projects. Geocadinal has addressed these needs in a dedicated near shore survey unit that offers a wealth of specialist expertise and affordable near shore hydrographic and geophysical survey services. Our survey personnel have been trained in the multidiscipline of surveying, equipment operation and maintenance and the processing and presentation of results.
Near-shore survey capabilities include:
- Single beam and multibeam echo sounder operations for detailed bathymetric charting in support of engineering and construction projects, navigation surveys, resource evaluation and conservancy.
- Side scan sonar surveys for detailed seabed mapping and the location and identification of man-made objects such as debris, shipwrecks, and sub-seastructures.
- Seismic profiler surveys for the investigation of sub-sea geology.
- Pre-route surveys for sub-sea cables and pipelines. Detailed corridor mapping provides the essential raw material for the design and installation of linear structures in shallow water.
- Acoustic inspection surveys for sub-sea installations, pipelines and cables.
Navigation Services
Precise positioning is fundamental to offshore survey engineering operations. Geocadinal Integrated Services Ltd provides a wide range of navigation services for both surface and subsea positioning. Surface positioning is provided by high precision differential GPS and subsea by the use of specialist underwater positioning systems. Through the application of innovative techniques, combining these specialized systems and advanced software solutions, Geocadinal has provided a quality controlled and cost-effective service to the offshore industry for more than a decade
Geo-Swath Multi-Beam System
Geocadinal has been regarded as “the specialist” in multi-beam bathymetry mapping and we have excellent references for our efficient, high accuracy seabed mapping projects. GISL has equipment and competent Personnel to perform hydrographic mapping surveys. Our expertise on seabed mapping and knowledge of the IHO requirements enables us to perform high quality hydrographic surveys. The acquisition, processing and presentation of technical data relating to surface and subsurface marine environments is critical to several over-water operations, including the planning, installation and maintenance of pipelines and cables, coastal construction projects, infrastructure maintenance, navigation and the sustainment of marine ecologies. GISL Multi- beam system, Geo-Acoustics Multi-beam Echo Sounder (MBES) is a swath bathymetry system that can be used in shallow water and depths of up to 100m. It uses an interferometric system to accurately measure water depths. It can measure swaths of about 12 times water depths.
Geo-Swath Multi-beam Unique features
The Geo-Swath Plus system comprises of a PC Based data acquisition and processing unit, two transducers, associated cabling and all necessary software so that when interfaced to appropriate peripheral sensors, the user can acquire, process, display, present and print high resolution bathymetry and Side Scan data.
Cable & Pipe lay Support Services
